Marvin Bagley III needed help off the court on Tuesday after a non-contact knee injury during a preseason game against the Oklahoma City Thunder.
The Detroit Pistons forward was back-pedaling in the lane to establish defensive position during a Thunder fast break. He planted his left foot, which slipped on the Pistons' home floor. His right foot remained planted, and his knee twisted awkwardly.
Bagley clutched his right knee in pain and eventually needed help off the court. The Pistons later ruled him out for the game.
